A wind-driven power plant has a mast that is arranged as two tubes installed in telescopic way, connected in hinged way with thrust bearing. The lower tube has larger diameter, its upper part is connected with four guys to anchors fixed in earth, and the lower end rests on foundation in hinged way. The ends of the tube are connected by four rods that go from the end of the tube with cross piece, with formation of spatial truss. The upper tube has smaller diameter, at its upper end horizontal axle is fixed, this is hinged to wind wheel of bicycle type. The wind wheel is arranged as connected to each other two-row bushing, spokes and rim. Face area of the rim is covered with rigid cowl, and at the outer surface of the rim set of blades if fixed. Free ends of the blades are connected to each other with outer rim with bended edge as confuser. The wind wheel is connected by gearing to electric generator fixed to the tube with a holder. To the tube with the middle section guide rod is attached, with guide blade at the end, this can rotate in free way within right angle between two restrictors arranged as rods fixed with the ends to the tube in horizontal plane. Guide rod is pressed to one of restrictors, it is parallel to axis of the working wheel. Free end of the restrictor is connected to load with cable that goes through block at the middle section of the guide rod and block at its free end. Free end of the other restrictor is connected to parachute with cable that goes through the block at the middle section of guide rod and guide ring at its end. |
